HORIZONTAL PACKAGE AIR CONDITIONNERS 50HB/HF
Electronic control CARRIERrtc basic This control is basically comprised of a control board, a TCO user terminal, a graphic maintenance terminal pGD1 (optional) and sensors. TCO user terminal This terminal allows the conﬁguration of the unit operating mode, the visualization of different temperatures of the installation, the view of alarms codes in the display and the timer programming. This terminal has an ambient temperature probe by standard and optionally may be replaced by a return air probe connected in the control board. PGD1 maintenance terminal (optional) This terminal incorporates a LCD display and, by texts, facilitates the initial scheduling of the unit, the modiﬁcation of the operating parameters and the description of the alarms produced. Main functions Selection of the operating mode: COOLING, HEATING, AUTOMATIC, FAN and DEHUMIDIFICATION. - Modiﬁcation of the setpoint - Permanent control of the operating parameters - View of the values measured by the probes - Timing of the compressors - Defrosting management (in heat pump units) - Anti-ﬁre safety - Control of the outlet temperature - Compressor discharge temperature control by probe - Compensation of the setpoint in accordance with the outdoor temperature - Timer and weekly programming - Failure diagnosis and main alarm - Counters of the number of starts and operating hours of the unit’s components Optional functions - Control of the auxiliary electrical heaters - Detection of clogged ﬁlters and management of air ﬂow controller - Connection to a centralised technical management system (BMS) for supervision using a BMS card especiﬁc for the communication protocols Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex, Modbus TCP/IP, BACnetTM Ethernet, TCP/IP, SNMP V1-2-3, FTP y HTTP.
Inlet air conditions
Minimum Indoor coil Maximum Minimum Outdoor coil Maximum
14 ºC WB 22 ºC WB 12 ºC* 48 ºC
10 ºC 27 ºC - 6 ºC WB ** 15 ºC WB
With control of the condensation pressure operating up to -10ºC. When the outdoor temperature is usually below 5ºC WB it is recommended installing a support element.
